cPanel is the most widespread Control Panel instrument on the hosting market. It is feature-rich and it has an easy-to-use interface that will supply you with full control of your sites. It is easy to manage files, e-mails and databases, take a look at usage statistics, set up script-driven applications, etcetera. This software is preferred by many web hosting companies, because it also has a reseller counterpart called WebHost Manager (WHM). The aforementioned software instrument will offer you a web-based graphical interface, through which you'll be able to manage lots of server-side settings, generate web hosting packages or new client accounts and adjust their features with just a couple of clicks. You may also install different modules and applications, modify DNS records, brand all of the cPanel accounts that your customers will get, create and remove features from their Control Panels, etcetera. cPanel and WHM are supported by nearly all billing applications out there, so this is one of the top platforms when you want to become a reseller.
